T!he gear is fine, the room is not! If it's the room, why is bass in movies ok? I would think that it's a source issue. Quote Link to comment Share on other sites More sharing options...
MEH Synergy Posted October 24, 2018 Share Posted October 24, 2018 +1. I think what I stated above will cover the easiest to troubleshooting first. Quote Link to comment Share on other sites More sharing options...
nitrofan Posted October 25, 2018 Share Posted October 25, 2018 Could it be that you have your sub set to play lfe only? There is a lot of itin most movies but none or very little in most music 1 Quote Link to comment Share on other sites More sharing options...

There is a lot of itin most movies but none or very little in most music That is a very interesting question. My Onkyo manual states the following in the Troubleshooting section: ■■The subwoofer produces no sound • When you play source material that contains no information in the LFE channel, the subwoofer produces no sound. • Make sure the speakers are configured correctly. I have the sub out of my AVR going to the LFE input of the R-115. I'm not quite sure of another way to connect them. Hopefully, I'll have some time this weekend to tinker.

There is a lot of itin most movies but none or very little in most music I really think you may have solved this. I received my R-51PM speakers today. They are for my workout room and replace "The Three" that I returned. Once they were up and running, I was even less impressed with these than with "The Three". I actually think "The Three" sounds better. IMHO, neither is worth $500... At least the R-51PM's have a sub out so I could dust off and use my KSW-15. When the sub out of the R-51PM's were connected to the LFE input of the KSW-15, it barely moved and was unimpressive. Thanks to your post, I changed from the LFE input to the standard L/R input of the sub (I tried both the L and the R). Wow!!! Night and day difference! I had to drop the level on the sub after doing so. The R-51PM's combined with the KSW-15 sound PHENOMENAL. It's deceptively loud because the music is so clear at high volume that you have to shout over it to be heard yet there is no distortion. THIS combo sounds like a Klipsch system. I'm guessing once I do the same with the R-115, I'll see the same response difference in my Living Room for listening to music. It will probably be tomorrow or Sat before I can test it but based on tonight's experiment, I believe you may well have nailed the issue. Question. Would it make a difference to buy a Y splitter so the single sub out goes into both the L and R inputs or is it OK to just go into either given that bass it typically mono? I wish I had a Y splitter to experiment with but don't. Quote Link to comment Share on other sites More sharing options...
nitrofan Posted October 25, 2018 Share Posted October 25, 2018 It will give you more gain but will not change the maximum output of your sub Quote Link to comment Share on other sites More sharing options...

I've cleaned up enough debris when it's connected to LFE. My thought was to ensure any <120Hz signals from either channel reaches the sub.

Also most newer Denon and Marantz receivers have an entire separate set of settings for 2-channel. You can choose to do whatever you want with it. If the bass is boosted 10 db on multichannel and it's flat on 2 channel, yeah it will be on but he would complain in this same way. Quote Link to comment Share on other sites More sharing options...
